Mitochondria specific oxidative injury by near-infrared energy transfer nanoclusters for amplified photodynamic potency

To promote practical applications of photodynamic therapy, near-infrared (NIR) photosensitizers are manufactured based on fluorescence resonance energy transfer (FRET) between donors of anti-stoke NIR upconversion nanoparticles and acceptors of photodynamic chlorin e6. The manufactured FRET constructs displayed deep tissue penetration and FRET activation under 980 nm irradiation. Furthermore, surface decoration with mitochondria-targeting (4-marboxybutyl) triphenyl phosphonium bromide (TPP) led to mitochondrion-targeted accumulation of singlet oxygen resulting in potent cell apoptosis. Notably, in vivo anti-tumor test validates the complete ablation of intractable solid tumors based on single-dose treatment of our proposed photodynamic constructs. Therefore, the obtained results herald the tempting perspective of our carefully engineered photodynamic constructs, which could have broad utilities in clinical treatment of intractable premalignancies.

Performance analysis of a dual component generator-condenser of an absorption heat transformer for water desalination

The purpose of this work is to evaluate the behavior of a novel dual component: generator-condenser (GE-CO) applied to a single-stage absorption heat transformer for water desalination (SAHT-WD) by simple evaporation that operates with a LiBr-H2O mixture. The GE-CO consists of two sections located in the same shell, where desorption and condensation occur simultaneously. The evaluation has been divided into an experimental and a theoretical analysis. The experimental analysis is focused on determining the operating conditions that favor the performance of the GE-CO and the overall SAHT-WD. To estimate the heat transfer coefficients and wetting efficiencies based on the experimental results, a mathematical model that considers variation of the inlet absorption mixture stream, the refrigerant, the heating and cooling water was constructed. The results indicate a good coupling between the GE-CO and the AHT, with maximum values of COP and desalinated water flow of 0.49 and 3.91 x 10(-4) kg/s. The maximum specific desalination rate (SDR) of the AHT-WP was 1.10 x 10(-4) kg/s/kW. Both in the GE and CO, the heat transfers of the film of the absorbent mixture and the refrigerant respectively, limit the heat transfer process.

Synthesis of Spherical Nanostructured gamma-Al2O3 Particles using Cetyltrimethylammonium Bromide (CTAB) Reverse Micelle Templating

We demonstrated the synthesis of spherical nanostructured gamma-Al2O3 using reverse micelle templating to enhance the surface area and reactant accessibility. Three different surfactants were used in this study: benzalkonium chloride (BZK), sodium dodecyl sulfate (SDS) and cetyltrimethylammonium bromide (CTAB). We obtained spherical nanostructured particles only using CTAB that form a reverse micelle emulsion. The particles have wide size distribution with an average size of 2.54 mu m. The spherical particles consist of nanoplate crystallites with size 20-40 nm randomly arranged forming intercrystallite spaces. The crystalline phase of as-synthesized and calcined particles was boehmite and gamma-Al2O3, respectively as determined by XRD analysis. Here, the preserved particle morphology during boehmite to gamma-Al2O3 transformation opens a facile route to synthesize gamma-Al2O3 particles with complex morphology. The specific surface area of synthesized particles is 201 m(2)/g, which is around five times higher than the conventional gamma-Al2O3 (Aldrich 544833). Spherical nanostructured gamma-Al2O3 provides wide potential applications in catalysis due to its high density closed packed structure, large surface area, and high accessibility.

Identification of novel inhibitors of the ABC transporter BmrA

The resistance of microbes to commonly used antibiotics has become a worldwide health problem. A major underlying mechanism of microbial antibiotic resistance is the export of drugs from bacterial cells. Drug efflux is mediated through the action of multidrug resistance efflux pumps located in the bacterial cell membranes. The critical role of bacterial efflux pumps in antibiotic resistance has directed research efforts to the identification of novel efflux pump inhibitors that can be used alongside antibiotics in clinical settings. Here, we aimed to find potential inhibitors of the archetypical ATP-binding cassette (ABC) efflux pump BmrA of Bacillus subtilis via virtual screening of the Mu.Ta.Lig. Chemotheca small molecule library. Molecular docking calculations targeting the nucleotide-binding domain of BmrA were performed using AutoDock Vina. Following a further drug-likeness filtering step based on Lipinski’s Rule of Five, top 25 scorers were identified. These ligands were then clustered into separate groups based on their contact patterns with the BmrA nucleotide-binding domain. Six ligands with distinct contact patterns were used for further in vitro inhibition assays based on intracellular ethidium bromide accumulation. Using this methodology, we identified two novel inhibitors of BmrA from the Chemotheca small molecule library.

Effect of Sepatronium Bromide (YM-155) on DNA Double-Strand Breaks Repair in Cancer Cells

Survivin, as an antiapoptotic protein often overexpressed in cancer cells, is a logical target for potential cancer treatment. By overexpressing survivin, cancer cells can avoid apoptotic cell death and often become resistant to treatments, representing a significant obstacle in modern oncology. A survivin suppressor, an imidazolium-based compound known as YM-155, is nowadays studied as an attractive anticancer agent. Although survivin suppression by YM-155 is evident, researchers started to report that YM-155 is also an inducer of DNA damage introducing yet another anticancer mechanism of this drug. Moreover, the concentrations of YM-155 for DNA damage induction seems to be far lower than those needed for survivin inhibition. Understanding the molecular mechanism of action of YM-155 is of vital importance for modern personalized medicine involving the selection of responsive patients and possible treatment combinations. This review focuses mainly on the documented effects of YM-155 on DNA damage signaling pathways. It summarizes up to date literature, and it outlines the molecular mechanism of YM-155 action in the context of the DNA damage field.

Glucose-Derived N-Doped Graphitic Carbon: Facile One-Pot Graphitic Structure-Controlled Chemical Synthesis with Comprehensive Insight into the Controlling Mechanisms

Modification of graphitic structure chemistry and physics affords the N-doped graphitic carbonaceous materials (NGCMs) superior and novel functional properties, which is essential for substantial development of applications based on such materials. The present research provides novel simple structure-controlled chemical synthesis of NGCM. NGCM is grown from cyclic polymerization of glucose molecules upon hydrothermal treatment, employing Cetyltrimethylammonium bromide (CTAB) and ammonia as structure-directing agents. Hydrothermal temperature and CTAB dose were manipulated and the produced graphitic structure has been explored in terms of oxidation state, N-doping, surface functionalization with CTAB and morphology. NGC derivatives of various structural features are obtained. Products range from oxidized graphitic carbon of mixed micro-sized sphere/sheet morphology to highly-reduced graphene-like nanosheets; the C/O atomic ratio increases from 8.2-12.4 and sheet thickness downs from 30 mu m- similar to 1 nm. Also, N-doping configurations and graphitic surface functionalization by CTAB are greatly influenced. CTAB plays the key role in setting the graphitic structure characteristics. Additionally, ammonia has a modest effect. Understanding of the controlling mechanisms is focused. The effective and ease control of graphitic structure via this facile, economic and ecofriendly synthesis approach, can benefit the design of NGCM with tuned functional properties for specific applications in technological industries.

Curcumin Promoted miR-34a Expression and Suppressed Proliferation of Gastric Cancer Cells

Background: To investigate the effects of curcumin on miR-34a and proliferation of gastric cancer cells. Materials and Methods: Human gastric cancer cell line SGC-7901 was divided into control, curcumin, miR-34a agomir (miR-34a), miR-34a agomir negative control, and curcumin combined miR-34a antagomir (combine) groups. 3-(4, 5-dimethylthiazolyl-2)-2, 5-diphenyltetrazolium bromide assay, scratch damage test, and transwell assay were used to detect cell proliferation, migration, and invasion. The cell apoptosis and cell cycle were detected by flow cytometry. Western blot was used to detect the expression of B-cell lymphoma-2 (Bcl-2), cyclin-dependent kinase 4 (CDK4), and cyclin D1. Terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling was used to detect apoptosis of tumors and Western blot was used to detect the expression of Bcl-2, CDK4, and cyclin D1 in tumors. Results: The results showed that curcumin markedly increased the content of miR-34a microRNA (mRNA) in SGC-7901 cells, inhibited proliferation, migration, and invasion of SGC-7901 cells, when compared to control group (p < 0.05). Compared with control group, curcumin significantly inhibited cell cycle progression in G0/G1-S phase, increased the cell number of G0/G1 phase, and downregulated the Bcl-2, CDK4, and cyclin D1 protein expression in cells and tissues (p < 0.05). After transfection of miR-34a agomir or antagomir into cells it was found that miR-34a agomir and curcumin had similar effects on resisting malignant biological behavior. Curcumin combined with miR-34a antagomir could weaken or reverse the above results. Conclusions: Curcumin could inhibit the proliferation and induce apoptosis of SGC-7901 cells. Its mechanism might be related to the miR-34a expression in cells, thus affecting the expression of Bcl-2, CDK4, and cyclin D1. Interested yet?

Rotation-restricted strategy to synthesize high molecular weight polyethylene using iminopyridyl nickel and palladium catalyst

Most of the iminopyridyl Ni (II) and Pd (II) catalysts are reported to oligomerize ethylene or yield very low molecular weight polyethylene. Moreover, the molecular weight of product is not sensitive to ligand sterics. In this contribution, we demonstrate that the bulky rotation-restricted substituents incorporated into iminopyridyl Ni (II) and Pd (II) catalysts that provide the right orientation are highly effective in retarding the chain transfer. Thus, (2,6-bis(10,11-dihydro-5H-dibenzo[a,d][7]annulen-5-yl)-4-methylphenyl)-1-(pyridin-2-yl)methanimine nickel (II) bromide (Ni3) and (2,6-bis(10,11-dihydro-5H-dibenzo[a,d][7]annulen-5-yl)-4-methylphenyl)-1-(pyridin-2-yl)methanimine palladium (II) methyl chloride (Pd3) with the phenyl substituents fixed in the diarylmethyl moiety produce polyethylene or functionalized polyethylene (ethylene-MA copolymer) with high M-n values up to 2.5 x 10(4) g mol(-1), while allowing the high MA incorporation (3.2%-13.8%). In addition, the effects on the (co)polymerization behavior as a function of rotation-restricted substituent variations (free rotation, restricted rotation and fixation) were systemically studied. As a result, various molecular weight polyethylene and ethylene-MA copolymer with high MA incorporation ratio were also obtained in this system.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 2032-35-1. HPLC of Formula: C6H13BrO2.
